WATER CIRCULATOR FOR INTERNAL-COMBUSTION ENGINES.

Application filed Jecember 29, 1920. Y Serial No. 433,791.

To all whom t may concern.'

Be it known that weVGEoRGE A. SPARKS and VERNON C. SPARKS, citizens of the UnitedStates, residing at Lodi, vin the county of San Joaquin, State of California, have invented certain new and useful 1mprovements in lVater Circulators for Internal-Combustion Engines; and we do declare the following to be-a full, clear, and exact Y description of the saine, reference being had to the Aaccompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in devices for circulating the water in the coolingsystems of internal combustion engines, being especially intended to be used on engines which are not equipped with pumps and depend on the thermo-Siphon principle of water circulating.- a The principal object of lour inventionis to provide an impeller device which will positively circulate .the water, and raise it to a considerable height; and which will take the form of an attachment which -replaces one of the standard pieces ofv equipment on some engines, such as the Ford, and for which we have illustrated the, device in this application. W e Ahave also arranged to run the device from the fan belt or pulley as regularly7 equipped without dis-- turbing the latter in any way.

Another' object is therefore gained and accomplished byv such a structure, this being the provision of a power operated unit which Vdoes not necessitate dismantling and rebuilding the engine to accommodate the saine, as is unfortunately true of'a great manydevices, admirable in themselves, but which are precluded from being in general use on account of this fact.

Our devicev however may be installed on anengine already built,'in but a very vfe'w minutes, which feature alone shouldappeal to prospective users, who are naturally dubious to try out any devices which necessitate alternations being 4made on their engines. A further object ofthe invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes which it is designed.

These objects we accomplish by means of such structure Vand relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of refH erence indicate corresponding parts in thel several views.Y M l F ig. l is ra' fragmentary outline of the front end of a motor-car engine, showing our improved device installed thereon.

Fig. 2' is an enlarged view of the device partly in section.

F ig. 3 is an end elevation thereof.

F ig. 4 is a sectional view of a modified form of lthe device.:

Y Referring-now moreparticularly to the. `characters ofreference on the drawings, the

numeral 1 denotesthe engine proper, having the usual water outlet manifold 2, leading to the radiator and the cooling fan 3 driven by a belt 4 from a pulley 5 onI the crank shaft 6. l

The manifold 2l on the Ford and other engines, terminates at the forwardl end of the cylinder casting, andhas a separate elf bow secured thereto, which elbow projects upwardly and is connected` to a rubber hose 7 which leadsto the radiator (not shown).

This elbow we remove, and replace it with yanother elbow 8 ofthe same gen-eral shape and size, but provided with a horizontal bearing boss 9 in central alinement with the opening of said elbow int-o the manifold 2. Journaled ,in the boss 9 and also. `in* an outer and spaced boss 10.7supported by a bracket 11 formed integral with the elbow 8 is a shaft 12, held against longitudinal movement, `on the end of which inside the elbow are secured .impellers 13. There are preferably a pair of such impellers, which are in the `form of the usual screw type of propeller, andmay,.for cheapness and ease of manufacture be cut or stamped from sheet metal and held in;A spacedrelation on the shaft 12 by means of collars 14, and clamped in place by a nut 15. sponding blades of theseimpellers are sub- The correstantiallyl parallel to each` other, but are l preferably arranged. in staggered relation, the result being that water drawn in by the one nearestthe member 2is thrown against the. blades of the inner-'impeller member and by them diverted upwardly.

By this means we are able to raise the water, or keep the same in rapid circulation, i

in a much more efficient manner than would be possible with a single impeller, and thus Y maintain a very cool motor at all times.

The outer end of the boss 9 is provided i'io with a packing gland 16 and with a packing nut 17 while a grease cup 18 is positioned on the outside and communicates with the bearing surface of the boss 9.

On the shaft 12 between the ltwo bearings thereof is a pulley 19, preferably of the same type as the pulley 5, and which is slidable on the shaft within the limits of the bearings, being provided however with a set screw 2O so that it may be clamped in position.

By making this pulley hollow and open at one end, it may normally surround the nut 17 so as to bring it in vertical alinement with the pulley 5, while at the same time it may be unclamped and slid along the shaft so as to allow a wrench to be applied to the nut 17 when occasion demands.

To drive the pulley 19, a belt 21 passes around the same and also around the pulley 5 on the outside of the belt 6, so that there will be a good grip on the belt 21 without great strain or wear on the same, and without disturbing the original fan-drive in any manner.

In Fig. A another form of impeller is shown, having the form of a small centrifugal pump.

In this case the water outlet member is of special shapeas at 22, while the impeller 23 is of the usual centrifugal-pump vane form, being set in some distance from the line of connection with the manifold 2, and discharging into a spiral outlet 24 which is shaped at its upper end to receive the hose 7 thereover.

lIhe pulley 19a of this type is driven from the pulley 5 in the same manner as the first described style.

In either case, the operation, which is self evident, will be the same, and the installation of the device is a mattei' of minutes, without necessitating any structural changes being made to the engine, or the securing thereto of any parts requiring new holes, pads or other attachments being placed on the engine.

Although we have particularly described our device as being interposed in the cooling system adjacent the top or hottest part thereof, it will of course work equally well if interposed near the lowest or at any other intermediate point. .j

From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.

7While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a de `arture from the spirit of the invention, as .e-ned by the appended claims.

Having thus described our invention, what we claiin'as new and useful and desire to secure by Letters Patent is 1. A device of the character described comprising a hollow fitting adapted to be interposed in the water circulation line of a gas engine, said fitting having a horizontal inlet and a substantially vertical outlet, and a pair of driven `and spaced impellers of the blade type mounted in the fitting, one of said impellers being adjacent the intake and the other substantially in central alinement with the vertical outlet, the blades of one being staggered relative to the blades ofthe other, whereby the water is drawn through the intake by the adjacent impeller, and is then thrown against the blades of the other, to be diverted upwardly by the latter.

2. A water pump comprising a hollow open ended casing having a horizontal intake and a substantially vertical outlet, a shaft journaled in the casing and projecting toward the intake, and double impeller means on the shaft arranged to draw the water horizontally through the intake and throw'it directly through the outlet without interference with the walls kof the casing.

3. A waterpump comprising a hollow open ended casing having a horizontal intake and a substantially vertical outlet, a shaft j ournaled in the casing and projecting toward the intake, and a pair of blade impellers mounted in closely spaced relation on the shaft; one impeller being located adjacent but inwardly of the intake and arranged to draw the water horizontally therethrough and the other being substantially in central alinement with the outlet and arranged to catch the water from 'the other' impeller and divert itdirectly toward the outlet.

4t. A water pump' comprising a hollow open ended casing having a horizontal intake and a substantially vertical outlet, a shaft journaled in the casing and projecting toward the intake, and a pair of blade impellers mounted in closely spaced relation of the shaft; one impeller being located adjacent but inwardly of the intake and arranged to draw the water horizontally therethrough and the other being substantially in central alinement with the oulet and arranged to catch the water from the other impeller and divert it directly toward the outlet, and a bearing member for the shaft formed with andprojecting into the casing and against which the inner impeller abuts to maintain it in proper alinement with the outlet. j

In testimony whereof we have affixed our signatures. A Y
